add 'requests per second' in metrics result, I think the qps might be an important index of benchmark tool.
the constructor of Metrics should be passed the total amount of requests, but actually is new Metrics(cli.amount * cli.args.length). I think it should be new Metrics(cli.amount * cli.messages)
